    text
    copied!<p>I have an XML document and want to insert a new node at a specific spot using SimpleXML. </p> <p>The original XML is this:</p> <pre><code>&lt;epp xmlns="urn:ietf:params:xml:ns:epp-1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:ietf:params:xml:ns:epp-1.0 epp-1.0.xsd" &gt; &lt;command&gt; &lt;create&gt; &lt;domain:create xmlns:domain="urn:ietf:params:xml:ns:domain-1.0" xsi:schemaLocation="urn:ietf:params:xml:ns:domain-1.0 domain-1.0.xsd" &gt; &lt;domain:period unit="y"&gt;&lt;/domain:period&gt; &lt;/domain:create&gt; &lt;/create&gt; &lt;/command&gt; &lt;/epp&gt; </code></pre> <p>after <code>&lt;domain:create&gt;</code> I need to add the following node:</p> <pre><code>&lt;domain:ns&gt; &lt;domain:hostAttr&gt; &lt;domain:hostName&gt;&lt;/domain:hostName&gt; &lt;domain:hostAddr ip="v4"&gt;&lt;/domain:hostAddr&gt; &lt;/domain:hostAttr&gt; &lt;/domain:ns&gt; </code></pre> <p>How can I do that? I have tried this:</p> <pre><code>$xmlObj = simplexml_load_file('myXMLFile.xml'); $nsNode = $xmlObj-&gt;command-&gt;create-&gt;children(self::OBJ_URI_DOMAIN)-&gt;create-&gt;addChild('domain:ns'); $hostAttr = $nsNode-&gt;addChild('domain:hostAttr'); $hostName = $hostAttr-&gt;addChild('domain:hostName'); $hostAddr = $hostAttr-&gt;addChild('domain:hostAddr'); $hostAddr-&gt;addAtribute('ip', 'v4'); </code></pre> <p>On this first line, I'm getting this warning:</p> <blockquote> <p>Warning: SimpleXMLElement::addChild() [simplexmlelement.addchild]: Cannot add child. Parent is not a permanent member of the XML tree</p> </blockquote> <p>On the second line, and because of this, I'm getting:</p> <blockquote> <p>Fatal error: Call to a member function addChild() on a non-object</p> </blockquote> <p>Thanks in advance.</p> <p>Additional notes: - The php version is higher then 5.1; - I have successfully added child nodes later on this same XML.</p>
